Get to know Ethereum, the world’s second-largest blockchain — explore its key features, Smart Contract system, and the reasons why Ethereum continues to dominate the market.

What is Ethereum and where did it come from?

Ethereum is a smart contract–based blockchain launched in 2015 by Vitalik Buterin and his team. It was designed to expand the capability of blockchain technology beyond simple money transfers — enabling the creation of decentralized applications (dApps) and smart contracts that can operate without intermediaries.

Ethereum is often called the second-generation blockchain because it builds upon the foundation of Bitcoin, introducing features that support programmable logic and more complex transactions.

Key Terms Related to Ethereum (ETH)

1. Ethereum (ETH)

The main digital currency of the Ethereum network
Used to pay transaction fees and stake for rewards

2. Smart Contract

An automatic program that runs on Ethereum
Executes when conditions are met without intermediaries
Example: An NFT sale contract automatically releases tokens and transfers the NFT to the buyer once payment is complete

3. dApps (Decentralized Applications)

Applications that run on Ethereum in a decentralized manner, without a central server
Example: NFT games, DeFi exchange platforms

4. Gas Fee

The fee required to run a transaction or Smart Contract
The more complex the transaction, the higher the Gas fee

5. EVM (Ethereum Virtual Machine)

A virtual machine that runs all Smart Contracts and dApps
Makes Ethereum a blockchain that can run programs like a mini computer

6. Proof-of-Stake (PoS)

The transaction verification mechanism of Ethereum 2.0
ETH holders can stake ETH to help validate blocks and earn rewards (Currently, Thailand does not permit the staking of cryptocurrencies.)

7. Layer 2

Solutions that increase speed and reduce fees by connecting to the Ethereum Mainnet
Example: Arbitrum and Optimism are Layer 2 solutions for Ethereum

8. NFT (Non-Fungible Token)

Unique digital assets
Created and traded using Ethereum
Example: Digital art, music, or in-game NFT items

9. DeFi (Decentralized Finance)

Decentralized financial services on Ethereum
Example: Lending, depositing coins to earn interest, token exchanges

10. Staking 

Locking ETH to help verify transactions and secure the network 
Exchanging it for ETH rewards as passive income 
(Currently, Thailand does not permit the staking of cryptocurrencies.)

Ethereum is a blockchain developed as an extension of Bitcoin, not only for transferring coins but also for running automatic programs called Smart Contracts, which execute on their own when conditions are met without relying on intermediaries, making transactions transparent and verifiable.

For example, in NFT trading, the system automatically transfers coins and the NFT to the buyer immediately.

Transactions and running Smart Contracts on Ethereum require a fee called Gas Fee, which depends on the complexity of the transaction and the network congestion. If there are many users or complex transactions, the fee increases. Conversely, when the network is less busy, the fee is lower.

Ethereum Virtual Machine (EVM)

All operations occur on the Ethereum Virtual Machine (EVM), which acts like a machine running Smart Contracts and decentralized applications (dApps). This allows Ethereum to be a blockchain that can process programs like a mini computer, ensuring every transaction is securely verified and recorded on the network.

Ethereum is a blockchain widely used around the world because it can run Smart Contracts and support dApps, DeFi, and NFTs comprehensively, allowing users and developers to continuously innovate on the network.

Smart Contract: Automatic programs that run on Ethereum when conditions are met without relying on intermediaries.

dApps Ecosystem: Supports various types of decentralized applications, such as games, finance, and NFT marketplaces, enabling users to access services without a central server.

DeFi and NFT: Ethereum serves as a base for decentralized financial services, such as lending, token exchanges, and NFT trading.

Layer 2 Solutions: Tools like Arbitrum and Optimism help increase speed, reduce fees, and expand the network, enabling faster transaction processing.

Proof-of-Stake (PoS): A secure and energy-efficient transaction verification system where coin holders can stake ETH to help validate blocks and earn rewards.

Large Developer Community: Drives continuous innovation, tools, and network upgrades.

Bitcoin (BTC) and Ethereum (ETH) are two digital currencies that play important roles in the cryptocurrency ecosystem. Although both use blockchain technology and are decentralized, they have clearly different purposes and features.

Bitcoin was created in 2009 by an individual (or group) using the pseudonym Satoshi Nakamoto, with the primary goal of being a digital currency that can replace cash for online transactions and serve as a reliable store of value.
Bitcoin uses the Proof-of-Work (PoW) transaction verification mechanism, which requires energy for mining and processing transactions. It has a maximum supply of 21 million coins, giving it characteristics similar to digital gold.

Both cryptocurrencies are important in the crypto ecosystem:

• Bitcoin focuses on being a store of value and a trusted digital currency.
  
  

• Ethereum focuses on being a platform for creating and running decentralized and transparent applications.

Comparison Table: Bitcoin vs Ethereum

Ethereum 2.0, or simply Eth2, is a major upgrade of the Ethereum network designed to address the limitations of the original Ethereum, particularly in transaction processing speed, security, and energy consumption.

Impact of Ethereum 2.0

1. Speed

Ethereum 2.0 uses Sharding technology, which divides the network into multiple parts, allowing thousands of transactions to be processed simultaneously. This greatly increases transaction speed and better supports high network usage.

2. Security

Ethereum 2.0 is designed to be more secure by using validators to verify transactions and blocks, reducing the chance of data tampering and increasing trust for the network and users.

3. Lower Energy Consumption

One of the key changes is the shift from Proof-of-Work (PoW) to Proof-of-Stake (PoS). This mechanism significantly reduces electricity usage for running the network, making Ethereum 2.0 more energy-efficient and environmentally friendly.

1. Ethereum is a flexible and versatile blockchain platform. It is not only used for transferring ETH coins but also serves as a key foundation for various applications and digital services, allowing users to easily access decentralized financial services, trade digital assets, enjoy blockchain games, and buy and sell NFTs.

Investing in Ethereum (ETH) is clearly different from investing in traditional assets. While ETH is considered a digital asset with growth potential, it has characteristics and risks that differ from gold, stocks, or real estate.

ETH vs Gold

Both can serve as a store of value, but Ethereum is much more volatile than gold. This means it has the potential for high returns but also carries higher risk.

ETH vs Stocks

Stocks provide growth and dividends, whereas Ethereum does not pay dividends but can grow in value through market demand and usage in DeFi, NFT, and dApps. ETH’s volatility is generally higher than that of average stocks.

ETH vs Real Estate

Real estate has low liquidity, requiring time to sell and manage, but its value is relatively stable. Ethereum can be traded instantly worldwide, offering high liquidity but with significant price volatility.

Ethereum vs. other investments comparison table

 

When comparing Ethereum with traditional assets such as gold, stocks, and real estate, it is clear that Ethereum is highly flexible. It can be traded 24/7 through online platforms, allows for low initial investment amounts, and offers the potential for high returns from the growth of the crypto market. However, it also carries high volatility and legal risks.

Gold, on the other hand, is a safe asset but may provide slower returns. Stocks have growth potential based on the business and the economy but are also subject to market volatility.

Real estate generates income from rent and the appreciation of property value according to economic conditions but requires high initial investment and has low liquidity.

Therefore, investment decisions should consider both the risks and opportunities of each asset type to build a balanced portfolio that aligns with the investor’s goals.

Safely storing Ethereum (ETH) is essential for investors of all levels to prevent loss or theft. Investors can choose to store their coins in a Hot Wallet or Cold Wallet, depending on convenience and the desired level of security.
